In the drawings, A represents a dial hav- Beneath the shafts 11W is mounted a double ing in its face a series of grooves, a a, in magnet, C, suitably connected with a battery,

, net 0.

A single magnet, D, is mounted beneath the worm-shaft I), and operates a lever, b loosely mounted thereon. A pawl, b on this lever engages a ratchet, b, on the worm-shaft, and causes each movement of the lever to be communicated to said worm-shaft and partially rotate it. The object is to require a great number of movements of the lever and a similar number of movements of the device by which-it is operated to accomplish a single revolution of the worm-shaft.

Forward and backward movement'of the hands upon any one of the shafts may be caused by the revolution of the shafts b b, respectively,which movement is accomplished by throwing either of thewheels b b into ongagement with its particular shaft by means of the clutch previously mentioned. For instance, should it be desired to cause the hand on the sleeve a to move forward one point on the dial, the current of electricity is caused to pass through the magnet O,'energizing it and causing the lower end of the lever to be attracted thereto. This causes its upper end to be thrown in the opposite direction, whereby the clutch b engages the worm-wheel l)" and secures it to the shaft on which it is mounted. The weight b upon the upper end of the lever causes it to remain in this position when the attraction upon its lower end has been removed. The current passes through the portion 0 of the magnet, through the connection (Z to the magnet D, or through the magnet c and the connection (1, according to the. direction in which the hands are to be operated.

The passage of a current through themagnet D attracts the lower end of the lever b", the pawl thereon engaging the ratchet on the worm-shaft I), causing a partial rotation of the worm. This movement is transmitted to the shaft 1) through worm-wheel b and by a wheel, 73 is transmitted to the sleeve a. During this operation the wormvheel b is "also rotated; but as its clutch has been withdrawn from it it is free to revolve upon its shaft. The gear-wheel If is also being moved by the main gear-wheel Z), with which it'in'eshes; but itis also permitted to revolve upon its shaftby means of a pawl and ratchet there provided, as shown. Thus it will be seen that the upper shaft alone is in effective operation and forward movement of the hand is insured. The number of teeth in theratchet b aswell as the pitch of the thread of the warm and number of teeth inthe worm-wheelsand other gear-wheels, may be arranged to pro'viae for tli'eproper number of movements of the lever b, and consequently a similar numb-Bret depressions of the key or other instrument used to make and break the electric current, and

on the worm-shaft and carrying,

it is "desirable that a large number of movements be given the key to move the hand being operated but one point upon the face of the indicator. To reverse the movement of the hand, the magnet c is energized in order to attract the lever and throw the lower train of wheels into and the upper train out of operation. The operation of the worm is the same in'eaeh instance.

The mechanism here shown and described operates but one hand, .B-that carried by the shaft a. Each shaft is provided with similar mechanism, and may be operated through independent wires, all being bound in a cable and carried from one indicator to another. The arrangement of the gearing, as here shown, had been designed to necessitate about twenty depressions of the "key to cause the hand to move one space upon the face of the dial.

The disks a a, preferably made'of paper, are printed or otherwise marked to suit the character of quotations beinggi'ven, and'may be removed and replaced at pleasure. The

larger hands, 3' B indicate the full points, while the smaller hands, B" B, indicate fractions of points. It is intended that the longest hand, B, shall indicate present fluctuations of stock in full points, while the hand 13 in- Th e. hand s B B indicate the figures at which the stock was held when selling began, or at what the bidding ceased on the day previous.

111 Fig. 6, I have illustrated a series of indicators representing various markets,each of which of course is operated independently.

As a means'for operating the varioushands, I have here shown, for'convenience, the ordinary key and sounder used in telegraphy; but I do not wish to confine myself to the use of this instrument, since it is obvious that various devices may be used for this purworm whecl, substantially as described.

2. In an indicator, a dial, a hand mounted on a shaft carrying a gear-wheel,gear-wheels meshing therewith mounted on independent shafts, each caused to rotate in one direction with the shaft upon which it is mounted, a worm-wheel mounted upon a shaft, a orm meshing with the worm-wheel, a lever 7 ed pawl'engaging to rotate upon said worm shaft, "anda magnet-"whose armature is carried by said lever, substantially as described.

3. In an indicator, a main shaft carrying a clutches carried by a lever attached to said shafts, and a double magnet electrically connected, between which the lever extends, and means whereby a current of electricity may be caused to pass through either magnet for the purpose of operating the lever, substantially as described.
